አማርኛ Hedging closes or reduces a position by betting the other side: lay the team you backed ante-post, back the draw against your winning accumulator's last leg, cash out (which is just the bookmaker hedging for you, at their price). Done at fair odds, a hedge converts variance into a certain number.
The cost is paying margin on a second bet. Systematic hedging of every winning position is a tax on your own success; the honest uses are rare and specific — locking a life-changing accumulator, or exiting a position whose premise died with the team news.
£10 four-fold at 15.0 has three legs won; the last leg's opponent trades at 2.5 on an exchange. Laying/backing to equalise locks ≈£45 whichever way the last match goes, against £150-or-nothing unhedged. Whether that trade is right depends on the price, not on nerves.
